Abstract

Cette antenne (101) radiofréquence multibandes commutée est configurée pour rayonner et/ou capter des signaux radiofréquences sur au moins une première et une deuxième fréquence de fonctionnement, dont le rapport est sensiblement égal à une puissance entière de deux. Le corps d'antenne (102) comprend au moins un premier et un deuxième brin (111, 112) d'antenne. L'antenne comprend au moins un premier et un deuxième moyens de commutation (113, 114) respectivement disposés entre les premier et deuxième brins (111, 112) et entre deux sous-brins (1121, 1122) du deuxième brin (112). Les premier et deuxième moyens de commutation (113, 114) sont configurés pour être actionnés de façon simultanée et de façon analogue. La longueur du premier sous-brin (1121) d'antenne est différente d'une fraction d'une puissance entière de deux de la longueur d'onde associée à la première fréquence de fonctionnement. L'antenne (101) est accordée sur la première fréquence de fonctionnement, lorsque les premier et deuxième moyens de commutation (113, 114) sont dans le premier mode de fonctionnement, et accordée sur la deuxième fréquence, lorsque les premier et deuxième moyens de commutation (113, 114) sont dans le deuxième mode de fonctionnement.This switched multiband radio frequency antenna (101) is configured to radiate and/or pick up radio frequency signals on at least a first and a second operating frequency, the ratio of which is substantially equal to an integer power of two. The antenna body (102) includes at least first and second antenna strands (111, 112). The antenna comprises at least first and second switching means (113, 114) respectively arranged between the first and second strands (111, 112) and between two sub-strands (1121, 1122) of the second strand (112). The first and second switching means (113, 114) are configured to be actuated simultaneously and analogously. The length of the first antenna sub-strand (1121) is different by a fraction of an integer power of two of the wavelength associated with the first operating frequency. The antenna (101) is tuned to the first operating frequency, when the first and second switching means (113, 114) are in the first operating mode, and tuned to the second frequency, when the first and second switching means switches (113, 114) are in the second mode of operation.
